SPECIFICATION forming part of Letters Patent No. 535,253, dated March 5, 1895. Application filed fieptemher 10, 1894. Serial No. 522,626- (No model.)

To to whom it may concern.-

Be it known that 1, JOHN C. LOOK, a citizen of the United States, residing in San Jos, county of Santa Clara, State of California, have invented an Improvement in Oar-Couplings; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to that class of car couplings having a pivoted hook-head, with locking device or pin for locking the hook.

It consists of means or devices whereby said locking device can be operated by a lever from the side of the car.

It consists also of a device or means for holding open the pivoted hook-head,-preparatory to coupling.

The object of my invention is to make the coupling more effioient, by providinga means on the car for operating the lock, that shall be disconnected from the coupling, or of such limited contact that the coupling may be free to perform its required movements without interfering with the said lock operating means; and to provide means for automatically holding open the pivoted hook-head when the same has been opened, and also to provide means, by a short plunger, for operating from beneath the coupling those looking devices that do not extend through beneath the draw-head.

Heretofore, the connection between the lever and the look pin has been a flexible chain, or loosely pivoted link, vertically disposed, which would become chafed and broken; or the lever would be connected in other ways, whereby it would take the movements of the coupling. A crank shaft has also been suggested, to operate under a somewhat enlarged base of the pin; but in my improvement, an elongated movable base is formed under and rearwardly of the lock; the said base being produced bya rod,bar, or plate fulcrumed rearwardly, and extending forwardly to the lock; and the base of operation for the lever on the car, may be any part of the said rod, bar, or plate; and also a great number of locking devices have required the use of overhanging releasing levers to lift by chain or link from the top of the coupling, to which my elongated movable base would not be applicable, but the use of which can behad by the adoption of my plunger.

hereinafter mentioned.

Referring to the accompanying drawings for a more complete explanation of my invention,-Figure 1 is a perspective view of the coupling, showing the levers for uncoupling. Fig. 2 is a perspective view showing the lock released. Fig. 3 is a side elevation of a draw bar having another-form of look, a part being broken out, showing the look inside of the bar stem. Fig. 4 is a partial cross seotion of the end of the car. Fig. is also a partial cross section of the end of the car. Fig. 6 is a side view of a draw-head, a section being broken outshowing the device for holding the hook open. Fig. 7 is a top View of the draw-head with the holding blockin dotted lines. Fig. 8 is a sectional part taken on line 00-00 of Fig. 7, showing the holding block in position. Fig. 9 is also a sectional part taken on line m-zc of Fig. 7, showing the holding block out of position. Fig. 10 is a side elevation of a draw bar, a section being broken out, showing aform of lock with a plunger for operating from beneath. Fig. 11 shows the same form of look as Fig. 10, but in a'raised position. Fig. 12 shows the same form of lock as Fig. 11; the position of the lock showing the coupling operation. Fig. 13 is a front View of the plunger for raising the lock. Fig. 14is across section taken on line mwof Fig. 10 showing a difierent way of retaining the plunger in the draw-head, and also a dififerent but well known form of look.

A represents a form of coupling, of which Bis the pivoted hook head; 0, the locking pin for the hook head; D, the rod, bar, or plate on the draw bar and forming the movable base under which the lever E on the car acts. 1

F is the holding block for the hook head.

Referring to Fig. 1, the rod,bar or plate D is attached loosely to the lower portion of the pin O at c, and is held rearwardly in an eye a which is connected with the draw bar or as Now, this rod, it will be seen, follows the movement of the draw bar, and by being loosely held at both ends, it will also follow the movements of the lock. The lever E is journaled on the car, with its inner end e cranked in such a manner that it comes under the rod D.

The operation is as follows:-The lever E is twisted, causing the crank arm e to bear up against the rod D. This raises the rod D, whichbears up in the-eye a on the draw bar, and eye 0 in the locking pin, and the pin 0 being the movable part is raised, thus releasing the lock. By this arrangement, itwill be seen, that a is the fulcrum, e the power and c the weight to be raised. When the lever and rod are raised the coupling still has its required movements laterally and longitudi nally; the rod D sliding over the crank arm 6 as only the locking pin has the vertical movement. The rod D may be held in an eye attached to the car sill, as shown at a, Fig. 5, or it may hang loosely, and anything that serves as a fulcrum when power is applied may be used. The power may also be applied by a straight lever, as E in Fig. 5..

Referring to Fig. 2, it will be seen, thatthe rod D may beheld more securely in a fulcrum 0. on the draw bar, and not attached to the locking pin, but disposed beneath it; the same result being accomplished as in Fig. 1,namely, that of having therod D follow the draw bar to have its end act on the locking device when power is applied. 1

In Fig. 3, I have shown a different form of coupling to which my device is also applicable. Abar D is shown inside of the drawbar with the forward end employed as the lock, the rearward end being fulcrumed at 0. and therod D attached rigidly to the said bar D. at i, and extending forward,furnishes the base for the lever E. The base rodD may also be attached to any other part of the bar-D and furnish the base for the lever E bybeing extended to anysuitable place sufficiently forward of the fulcrum. This combination of levers may be used also .for other styles of couplings than those here shown.

The means for holding open the pivoted hook head are shown in Figs. 6, 7, 8 and 9. It consistsof a block F,.contained in a recess a in the draw head. This recess has vertical walls a to keep the block in position. The blockis swung at one end on a rod g, and the other end is free to rest on a part of the pivoted hook head near. the pivot pin h. This free end is so arranged that it is above the locking lever b which is free to move in and out. A notch-b isprovided in the hook head that comes under the block F when the hook is turned open, into which the blockfalls by gravity, as shown in Figs. 6 and 8; but the condition of this notch must be such that the block'oan be raised by the operationof coupling. For this purpose the notch is made with an inclined face 19 shown in Figs. 8 and 9, of such a slant that the sway of the car will not throw the block out, as that is the object to be overcome; but in a coupling operation, the pressure on the lever arm I) by the opposite coupling, throws the block F against the wall a and forces it up the incline and leaves it as shown in Fig. .9. Either the block or the notch can be inclined, or both may be inclined. v

In Figs. 10, 11, 12, 13 and 14,I have shown ger atZ.

a different way of reaching the locking de' vice D from beneath the draw-head. It consists of the pin or plunger held in the drawvhead under the lock rearwardly of the part occupied by the lever arm I) of the pivoted hook head. This plunger is held in an aperture 719' in the draw bar. The aperture may be extended by the walls 70 7.0 to give the pin an upright position; and is retained in the aperture by the pin Z passing through the walls 7.3 k and through an elongated eye or slot Z in the pin 70, shown in Fig. 18. The normal position of the plunger and lock is shown in Fig. 10, the uncoupled position is shown is Fig. 11, and the normal position of the plunger and coupling operation of the lock is shown in Fig. 12.

Fig. l tshows a different'way of, retaining the plunger 7a, which consists of lugs Z Z rest- .ing in recesses 7. ..Z in the draw-head; and

also another but .well known kind of lock. Otherv styles of lock may also be operated by this plunger.
